(as of Jul 18,2021 15:47:31 UTC – Details)



This is a simple-to-use compressed natural gas (cng) sensor, suitable for sensing natural gas (composed of mostly methane [ch4]) concentrations in the air. The mq-4 can detect natural gas concentrations anywhere from 200 to 10000ppm. Specification: 1. Signal output indicator. 2. Dual signals output (analog output and ttl output). 3. Ttl output signal is low level, allows to connect with scm directly. 4. Analog output 0~5v voltage. 5. High sensitivity. 6. Long working lifetime and stable performance. 7. Quick response and recovery. Technical data: 1. Chipset: Lm393 / mq-4 sensor. 2. Working voltage: Dc 3~5v. 3. Detecting range: 300~10000ppm.
